Public bug reported: I want to boot a Ubuntu LiveCD of 16.04 on a desktop box with an AMD A10-5800K AGP, Gigabyte FA-42A75M-HD2 motherboard, 8 GB of RAM, and no graphics card -- the Radeon HD 7660D graphics are done by the CPU. When I try to boot I get an error message, "ERROR: no UMS support in radeon module." When I edit the boot command line to add the parameter 'nomodeset' I first get an error message, "No UMS support on radeon module," then the familiar aubergine background with the ubuntu logo and the five dots below it changing from white to red and back again. After twenty or thirty seconds the background goes to black, I get the error message "No UMS support in radeon module," and the ubuntu logo disappears but the five dots continue. After another twenty or thirty seconds of that the screen clears, at the top is a line: "ubuntu 16.04 ubuntu LTS tty1," below that the line "ubuntu login:" and after a second or less the screen goes black and I can't do anything except reboot. I've tried old Live CDs, from 10.10 to 15.10, and they all boot fine.
